The Future of Food has been a key tool in the American and international anti-GMO grassroots activist movements and played widely in the environmental and activist circuits since its release in 2004. The film is widely acknowledged for its role in educating voters and the subsequent success of passing Measure H in Mendocino County, California, one of the first local initiatives in the country to ban the planting of GMO crops. Indicative of its popularity, the Future of Food showed to a sold out audience of 1,500 at the Castro Theatre in San Francisco in 2004, a benefit for Slow Food, where it was introduced by Alice Waters.
THE END OF SUBURBIA: Oil Depletion and the Collapse of The American Dream
http://www.endofsuburbia.com/
Since World War II North Americans have invested much of their newfound wealth in suburbia. It has promised a sense of space, affordability, family life and upward mobility. As the population of suburban sprawl has exploded in the past 50 years, so too has the suburban way of life become embedded in the American consciousness.
Suburbia, and all it promises, has become the American Dream.
But as we enter the 21st century, serious questions are beginning to emerge about the sustainability of this way of life. With brutal honesty and a touch of irony, The End of Suburbia explores the American Way of Life and its prospects as the planet approaches a critical era, as global demand for fossil fuels begins to outstrip supply. World Oil Peak and the inevitable decline of fossil fuels are upon us now, some scientists and policy makers argue in this documentary.
The consequences of inaction in the face of this global crisis are enormous. What does Oil Peak mean for North America? As energy prices skyrocket in the coming years, how will the populations of suburbia react to the collapse of their dream? Are today's suburbs destined to become the slums of tomorrow? And what can be done NOW, individually and collectively, to avoid The End of Suburbia ?
